Timber Species - Karri

Karri (Eucalyptus diversicolor)

Karri is a lively red with overtones from pale pink to rich reddish brown. Karriā€™s high density and hardwearing qualities make it highly sought after by architects.


Physical Properties

Dry Density: 900 kg/m³

Janka Dry Hardness: 9 kN

The Janka rating is the hardness level given to each species. The higher the number, the greater the hardness.

The natural colour variation within a timber species is normal and one of its most appealing attributes. The species samples shown here are indicative only and do not necessarily show the colour variation that can be naturally found in each species. It is recommended that large samples of the species be viewed in a timber flooring showroom when deciding on the species for a new timber floor.
